[ARC5] Arc-5 transmitter rack plugs.

[J Mcvey via ARC5]

Just when I thought things were moving along smoothly, I was presented with an odd obstacle on my transmitter rack.
It seems that the former owner changed the male plugs that interface with the back of the transmitter were changed to the receiver type. Although they look the same, apparently  the OD alignment of the pins is slightly larger for the transmitter receptacle.
Now what?????
